Hwclock is a program that runs under Linux and sets and queries the Hardware Clock, which is often called the Real Time Clock, RTC, or CMOS clock. This is the program that most Linux systems use to get the time from the Hardware Clock and set the System Time at boot time. This program works on ISA (Intel), Alpha, SPARC, and M68K systems with or without /dev/rtc.
The "EeePC-optimized Kernel for Ubuntu" project aims to produce a set of pre-compiled kernel packages that have been specially tailored to the EeePC's hardware and power usage, and to deliver these packages on a dedicated repository hosted by the author. Delivering these kernel packages over a Debian-style repository ensures that future updates and patches can be automatically downloaded to your EeePC as they're released. Current support is available for Ubuntu v8.04 (Hardy Heron) on the EeePC 700, 900, 900A, 901, 1000, and 1000H models.
biosdevname in its simplest form takes a kernel device name as an argument, and returns the BIOS-given name it "should" be. This is necessary on systems where the BIOS name for a given device (e.g. the label on the chassis is "Gb1") doesn't map directly and obviously to the kernel name (e.g. eth0).
